WLFO For High-Performance Low-Cost Packaging Of RFMEMS-CMOS


Navigating the trade-offs between performance, size, cost and reliability can be a challenge when considering integrated circuit (IC) packaging and the end-application. The integration of micro-electromechanical systems (MEMS), either monolithic or heterogeneous, introduces yet another level of complexity that has only recently been a major focus of multi-device packaging. Wafer-level fanout (W... » read more

New RDL-First PoP Fan-Out Wafer-Level Package Process With Chip-to-Wafer Bonding Technology


Fan-Out Wafer-Level Interposer Package-on Package (PoP) design has many advantages for mobile applications such as low power consumption, short signal path, small form factor, and heterogeneous integration for multifunctions. In addition, it can be applied in various package platforms, including PoP, System-in-Package (SiP), and Chip Scale Package (CSP). These advantages come from advanced inte... » read more

Challenges And Approaches To Developing Automotive Grade 1/0 FCBGA Package Capability


Automotive Grade 1 and 0 package requirements, defined by Automotive Electronics Council (AEC) Document AEC-100, require more severe temperature cycling and high temperature storage conditions to meet harsh automotive field requirements, such as a maximum 150°C device operating temperature, 15-year reliability and zero-defect quality level. Moreover, increased integration of device functionali... » read more

Side Wettable Flanks For Leadless Automotive Packaging


The MicroLeadFrame (MLF)/Quad Flat No-Lead (QFN) packaging solution is extremely popular in the semiconductor industry. It is used in applications ranging from consumer electronics and communications to those requiring high reliability performance, such as the automotive industry. The wide acceptance of this packaging design is primarily due to its flexible form factors, size, scalability and t... » read more

Development Of An Extremely High Thermal Conductivity TIM For Large Electronics Packages In 4th Industrial Revolution Era


The capability and diversity of high-performance microprocessors is increasing with each process technology generation to meet increasing application demands. The cooling designs for these chips must deal with larger temperature gradients across the die than previous generations. Dissipation of the thermal energy from heat generating parts to a heat sink via conduction occurs through a thermal ... » read more
